I am in the process of migrating from Gmail to Outlook; however, I am having trouble with the messaging function from the inbox. When I come to work and connect to our network, the messaging application refuses to sign-in. I have attached an image to highlight the problem. When I am on my home network, the messaging application works fine, but I am beginning to wonder if there is a network setting at work, which is preventing me from connecting.

I am curious, though, because the messaging function in my Gmail inbox was always functional on my work network. Why would messaging in Gmail function at work and not Outlook. Any help would be appreciated! I really like using Outlook, but I am afraid if this issue is not resolved, I may have to go back to using Gmail.

For those wondering, I am using IE 10 on a Lenovo laptop with Windows 7 SP1 (network administrator controls Windows Update).

Thanks!
